Beit known that I, G'UsT'Av B."PE'I'SCHE, `a subject of the Emperor' of Germany, residing. in'thecityy and county ol" Philadelphia, inthe State of Pennsylvania, have invented. a cer-'- tain new and useful Improvement in Blow'- Engines or Pumps', of: which'the' follow' mg is a true and yeX-act description, reference .being had to the accompanying' drawing.'

which forms a part thereof.

-The presentg invention relates' to blowing' 'engineso'rpumpa and 1particularly to blowing engines or pumps'o and of that typein which the cylinder proper and piston'are both movable and the movements ofthe cylinder'is relied upon to open and close'ports leading into" thecylind'er. ',lhe. object' of the present invention. is,` to

-. improve the mechanical construction of'such engines or pumps, and 'in particular to provide an eci'ent and eectively disposed outlet valve mechanism'controlling ythe escape of the 'Huid vpumped .or compressed bythe vThe various' features' of 'novelty which' characterize mjy invention are pointed'out with articularityy in the Iclaims'annexed to4 and orming a part of" this speciiication, For a better understanding of my invention,

however, reference'may 'be had to the ac-' companying drawin's and descr tive ,mat-
